Dance music superstar Avicii dead at 28

Avicii, seen here performing in the southern Swedish city of Malmo in 2016, was among the first DJs to break through in the mainstream as electronic dance music grew over the past decade from nightclubs to Top 40 radio

Avicii, one of the world's most successful DJs who helped usher in the global boom in electronic music but struggled to cope with the hard-partying lifestyle, died Friday in Oman, his representative said. He was 28.

Two years after his unusually early retirement from touring amid recurring health scares, the Swedish DJ was found dead in the Gulf sultanate's capital Muscat.

"It is with profound sorrow that we announce the loss of Tim Bergling, also known as Avicii," his management said in a statement, without specifying the cause of death.

"The family is devastated and we ask everyone to please respect their need for privacy in this difficult time. No further statements will be given."

Maitrai Joshi, a DJ at the Muscat Hills Resort, said he had spotted Avicii and understood the dance superstar was on vacation in Oman for the first time and had extended his stay.

"I saw him again the next day and again he was friendly, humble and took some photos," Joshi told AFP by email.

Avicii was among the first DJs to break through in the mainstream as electronic dance music grew over the past decade from nightclubs to Top 40 radio. He created a global hit out of Coldplay's "A Sky Full of Stars," to which he added a layer of energetic electronica.

He also helped produce Madonna's last album. On Instagram, the pop icon posted a picture of herself in the DJ booth with Avicii and wrote: "So Tragic. Goodbye Dear Sweet Tim. Gone Too Soon."

His biggest individual hits included "Wake Me Up," which went to number one across Europe in 2013 and featured the soul singer Aloe Blacc.

In 2015, he DJ-ed the wedding reception of Sweden's Prince Carl Philip and his bride Sofia. The couple mourned him in a statement, saying: "We had the honor to have known him and admired him both as an artist and the beautiful person that he was."

Swedish Prime Minister Stefan Lofven called Avicii "one of the greatest names of music in Sweden in modern times."

- Scene 'not for me' -

Avicii has spoken publicly in recent years about his health problems, including pancreatitis, triggered in part by excessive drinking.

The condition forced him to cancel shows in 2014 as he had to have his gallbladder and appendix removed.

In 2016, Avicii stunned fans by retiring from touring when he was just 26.

"The scene was not for me," he told music magazine Billboard after his decision.

"It was not the shows and not the music. It was always the other stuff surrounding it that never came naturally to me. All the other parts of being an artist," he added.

"I'm more of an introverted person in general. It was always very hard for me. I took on board too much negative energy, I think."

Avicii later returned to the more quiet life of a studio artist. Last year, he put out a six-song EP that featured British pop singer Rita Ora.

- 'Genius and musical innovator' -

The son of Anki Liden, a prominent Swedish actress, Avicii had his start uploading tracks on the internet and was discovered by Dutch superstar Tiesto, who invited him to play at his residency in the clubbing hub of Ibiza.

His breakthrough single, "Levels," adapted a sample of soul singer Etta James and earned him one of his two Grammy nominations.

He took his stage name from the Sanskrit word for the lowest level of hell in Buddhism, adding an additional "i" at the end.

In 2014, he was tied with Tiesto as the third top-grossing DJ in the world on the list of Forbes magazine, which estimated his earnings for the year at $28 million.

Pop star Charlie Puth paid tribute to Avicii as "a genius and a music innovator" and said he "really opened my eyes to what my production could one day sound like."

Deadmau5 -- an outspoken top DJ who had mocked Avicii when he quit touring so young -- offered his "sincerest and most heartfelt condolences."

"Banter aside, nobody can deny what he has accomplished and done for modern dance music and I'm very proud of him," Deadmau5 tweeted.

Fellow star DJ David Guetta, who collaborated with Avicii on "Sunshine," wrote: "We lost a friend with such a beautiful heart and the world lost an incredibly talented musician

"I know you had your demons and maybe this wasn't the right place for you sometimes, but we need to protect true artists like you at all costs because there are not enough left and we are losing too many," Diplo said.
